Clay, N.Y. -- A man from Costa Rica visiting family in the town of Clay was pulled from the bottom of a pool Monday morning by a neighbor who heard shouting, according to Deputy Herb Wiggins of the Onondaga County Sheriff's Office.

Pablo Umana, 44, was not breathing when emergency crews arrived at about 10:45 a.m. Monday. He is in critical condition, Wiggins said.

Wiggins provided the following account:

Umana told his relatives earlier Monday that he wanted to go swimming. Not knowing if he could swim, they asked him to wait for them to join him.

A little later, one of the family members heard a splash, went outside and saw Umana at the bottom of the pool. The person who saw Umana then began screaming.

Michael Vaughn, 23, who lives in Poseidon Circle, heard the screaming and jumped over a six-foot wooden fence, dove into the pool and pulled Umana out of the water.

The Clay Fire Department and NOVA Ambulance arrived and took Umana to the hospital, where he remains in critical condition. The incident occurred on Penelope Lane.
